Every Victorian Candle Co. candle is made with 100% natural soy wax. Cleaner burning than paraffin, it produces no black soot and won't leave marks on your walls or ceilings. Our soy wax also holds fragrance better, giving you a stronger, more consistent scent throw from the first burn to the last. And because we use cotton wicks and high quality fragrance oils, our candles burn evenly without tunnelling - so you get every hour of that 20 hour burn time
